HILARIUS KNOBEL, OF ZURICH, SWITZERLAND.

MEANS FOR GLAZIN'G ROOFS AND THE LIKE WITHOUT PUTTY.

Specification of Letters Patent.

Patented May 9, 1911.

Application filed October 24, 1910. Serial No. 588,698.

To all whom it may concern:

Be it known that I, HILARIUs KNoBnL, a citizen of the Swiss Republic, residing at Zurich, Switzerland, have invented certain new and useful Improvements in Means for Glazing Roofs and the Like Without Putty, of which the following is a specification, reference being had therein to the accompanying drawing.

Heretofore, in double glazing, each light or pane of glass was provided with special and independent parting-pieces or cross-bars, and this in glazings held by putty as well as in those not so held. Each light or pane had, therefore, to be constructed and held independently of the other light or pane, which was parallel to it, thereby increasing considerably the costs of construction and retarding the execution of a double glazed glass roof.

The present invention enables the construction of double-glazed glass roofs to be considerably simplified, by means of partingpieces or cross-bars for lights or glass panes fixed without utty, and which partingpieces or crossars are formed in such a manner as to carry, or support, an inner glazing and an outer glazing. To this end, these parting-pieces or cross-bars comprise two fittings or mountings connected the one to the other, an outer capping or rid e-piece and two detachable inner cover-pl ates or ridge-pieces, thereby permitting a ready re moval of the outer and inner lights or panes.

The accompanying drawing represents, in transverse section, and by Way of example, a constructional form of the invention.

1 and 2 are the two mountings or fittings. The small outer fitting 1, is placed saddlewise on the larger inner fitting 2. A bent bolt 3, provided with a nut 4, passes through the upper ends of the fittings 1 and 2, and secures them together. The fitting 1 is formed with gutters 5, provided with compressible packing, for instance, suitably impregnated hemp cords 6. The lights or panes 7, of the outer glazing, rest upon these packings, and are tightened up against them by means of the capping or ridge-piece 8 against which the nut 4 bears. The large fitting 2 has, on each side, a gutter 9 for running off water, and its lower part is inclosed by a shoe 10, formed with gutters 11 into which is inserted packing 12 for the inner lights or panes. A bent rod 13, screwthreaded at its ends, passes through slots in the mounting or fitting 2, and by means of nuts 14, screwed on the ends of this rod, the two lower capping or ridge-pieces 15 are tightened up against the pane 16 of the lower glazing. Hence the panes are also tightened up against the packing 12. The outer glazing, as well as the inner glazing, may be readily detached. Broken lights or panes may also be replaced without difficulty, and the inner lights or panes may likewise be very readily cleaned. Furthermore, according to this invention, in the construction of glazed ceilings not requiring any putty, no system of independent parting-pieces or cross-bars is necessary for the inner and outer glazings, the aforesaid parting-pieces or cross-bars being so disposed as to enable them to receive the two glazings, the construction is thus considerably simplified and great economy is efiected by reason of the incomparably more rapid execution of the work.

Having now described my invention, what-I claim and desire to secure by Letters Patent, 1s

1. A parting-piece or cross-bar for use without putty in double glazing and comprising two main fittings, the one being smaller than the other and imposed thereon, an outer detachable capping or ridge-piece, a bolt extending through the apices of the fittings and through the capping or ridgepiece, a nut arranged on the end of the bolt to hold the capping or ridge-piece against the panes which are fitted between said capping or ridge-piece and said smaller fitting, the latter being provided with gutters adjacent said panes, a pair of inner detachable capping or ridge-pieces arranged at each side of the larger fitting at some distance below the outer ridge-piece, a bent rod screw threaded at each end and extending through openings in the larger fitting and in the inner capping or ridge-pieces, and nuts secured on said bent rod to hold the inner capping or ridge-pieces against the panes which are fitted under said inner capping or ridgepieces, the larger fitting having gutters associated therewith adjacent to said lastnamed panes and opposite to said inner cap ping or ridge pieces.

2. A parting-piece or cross-bar for use without putty in double glazing and comprising two main fittings, the one being smaller than the other and imposed thereon, an outer detachable capping or ridge-piece,

a bolt extending through the apices of the fittings and through the capping or ridgepiece, a nut arranged on the end of the bolt to hold the capping or ridge-piece against the panes which are fitted between said capping or ridge-piece and said smaller fitting, the latter being provided With gutters adjacent said panes, a pair of inner detachable capping or ridge-pieces arranged at each side ofthe larger fitting at some distance below the outer ridgepiece, a bent rod screW- threaded at each end and extending through openings in the larger fitting and in the inner capping or ridge-pieces, nuts secured on said bent rod to hold the inner capping or ridge-pieces against the panes which are fitted under said inner capping or ridgepieces, and a shoe inclosing the lower end of the larger fitting and provided with gutilzleiis'l against Which the last named panes are In witness whereof, I have hereunto signed my name in the presence of two subscribing Witnesses.
